急性脑卒中发病时间的周期性差异(作者:___________单位: ___________邮编: ___________)【摘要】目的探讨急性脑卒中发病时间的昼夜、季节分布规律及临床意义。
方法对我院自2005年10月-2009年10月618例住院及门诊急性脑卒中患者发病时间进行统计分析。
结果急性脑卒中发病时间存在昼夜、季节分布的差异,昼夜分布6~12时间段为发病高峰,四季中夏季(6、7、8月)为脑梗死发病高峰季,冬季(12、1、2月)为脑出血发病高峰季,与期望发病率时间分布比较,差异有显著性(P0.01)。
结论通过改变人的某些日常行为和调整用药时间等措施降低急性脑卒中发病率。

There is significant difference(P0.01),compared with expected time distrbution.Conclusion The incidence of stroke can be decreased by modifing routine activity pattern and adjusting drug administering time.[Key words] brain stroke; onset; rhythm急性脑卒中发病时间存在昼夜、季节分布的差异,我们对我院自2005年10月-2009年10月618例住院及门诊急性脑卒中患者发病时间进行统计分析,旨在了解和探索其发病时间的昼夜、季节分布规律,以期通过改变人的某些日常行为和调整用药时间等措施降低急性脑卒中发病率。
